New Infra Red Sensor Technology for Portable Multi-gas Detector

The acclaimed Neotronics Impact multi-gas detector from Honeywell Analytics (UK) now benefits from an innovative new Infra Red (IR) replaceable sensor to further expand the best-selling portable unit’s gas sensing capability.

The Impact IR system uses Impact’s unique replaceable sensor cartridge concept to house the IR sensor alongside three other toxic and oxygen
deficiency sensors. Operators can now interchange cartridges to detect a variety of gases, especially those best monitored with the poison resistant, solid-state optical sensor technology.

IR allows the Impact to measure Carbon Dioxide (CO2), providing a stable, drift-free long life sensor method to detect CO2 in such diverse applications as waste water treatment, drinks bottling, fire suppression, leak detection and other industrial monitoring
applications. Methane and natural gas are now also detectable by IR, making it ideal for gas industries including offshore drilling, gas transmission and utility companies, and the sensor can also be configured to measure hydrocarbons at % LEL or % Vol levels for a
variety of industrial monitoring applications.

IR sensing also works in the absence of oxygen so the multi gas Impact Pro can now, enable an operator to briefly monitor prior to entry for leaks, purging efficiency or hull integrity in container vessels or pipes where there is reduced oxygen content or where an inert gas blanket has been laid over a combustible product. The multi sensor array is not intended for continuous monitoring in inert atmospheres as this may affect the accuracy of the other electrochemical cells.

The three IR sensors for % LEL, % Vol or % CO2 have the additional operational benefits of being automatically temperature compensated and
do not require gas calibrations as a separate reference channel continuously monitors the sensor’s performance. IR is also immune to sensor poisoning by sulphurous materials or silicones such as grease
and aerosols.
This new sensor further enhances the novel Impact Pro range of gas detector features such as the unique Enforcerâ„¢ field calibration device that requires no power to operate and the SafeLinkâ„¢ text alert system
to safely communicate between the operator and attendant in confined space entry applications. Long life NiMH batteries and a strong sampling pump option equip the water resistant IP67 Impact range as themost
flexible multi gas detector on the market.

“The Impact has built a world-leading reputation on its resilience, quality and adaptability using the sensor cartridge concept,” said Andi Thompson, Managing Director of Honeywell Analytics EMEA.

“The addition of an IR cartridge not only increases the scope of the Impact to ensure safety in an even wider range of environments, but reaffirms Honeywell Analytics’s reputation as the committed innovator in
gas detection.”
